In this paper, new structures of embedded internet remote control systems, which can control electo-mechanical systems, are developed. For this, remote interface system structure using embedded system are developed first, then the way of internet remote control and the PC program for the control are discussed. The developed syste in this paper can be applied to home automations such as to control entrance doors, lights, consumer electronics and other industrial applications. To show the example illustrations, in this paper, the deyeloped system has been applied to multiple motor control systems. The results show that the developed system can directly be applicable into the real industrial field.

In this paper, we have developed the web-based management system for greenhouse teleoperation. The remote control system consists of database, web-server, controller in greenhouse, and clients. The database in the server stores user informations and greenhouse conditions, and is used to manage user login and conditioning data. The management system developed by using Java applet, which is a client program for effective and easy management of greenhouse, monitors the greenhouse in real time. Master and driver boards installed in greenhouse control unit. Database on flowering to collect and analyze data exchanges data with the server. The greenhouse can be managed effectively by timer routine, repeat control within setting time, and algorithm of setting points. Also, the greenhouse conditions can be controlled by manual or remote controller (PC) through web browser in internet. Furthermore, all of the control devices of the greenhouse are managed by remote control using PC and checked via camera installed in greenhouse.

Recent technological advances in utilization and generalization of Internet have overcome some of the limitations of remote robot control range and real-time monitoring system. However, It needs Embedded system with control protocol or hardware which has avility to port the micro realtime operating system in robot control system communicate with remote controlled robot, because those system use the wireless LAM or Bluetooth as a network media. In this paper, we design and implement the wireless MODEM protocol and install it to the server system. Also, we implement a client system could control the remote robot through the server and we assure that this protocol and client/server system ate suitable for small size remote control system based on Internet.

An internet and network based software and related interface have been developed, which can remotely control and manage an on-site operating system. Developed software modules were composed of two parts: monitoring/management modules and control/diagnosis modules were developed for the network status, warehouse, production and selling status. Modules of control with diagnosis were developed for the on-site operating system and interface. Each module was integrated and the whole modules have been tested with an automatic mushroom grading/sorting system which was built in a laboratory. Developed software modules worked successfully without any uncommon situations such as system down caused by the software or data transfer error. Each software module was developed independently in order to apply easily to other existing on-site systems such as rice processing centers, fruit and vegetable sorting, packaging and distribution centers scattered over the country.

This paper presents a wired and wireless linked remote control system. Ethernet based network communication is used for long distance management and 2.4GHz RF network is adopted for the local area communication between the main network and the ballast. For the effective remote control and management including dimming using wired and wireless linked digital communication networks, control circuit of the ballast is implemented with fully digital circuit using MCU and EPLD. In this paper, the proper frame structure is proposed for the digital-remote lighting-control system and the detailed system configurations including fully digital controlled ballast for the induction lamp are described.

To secure abyssal resources, submarine environment should be firstly explored. On that occasion, the withdrawal of the instrument is of importance and the submarine ultrasonic wave should be stably identified regardless submarine environment and passive factor. In the existing control methods, the control informations, received from an observation instrument, are identified used by hardware and repeatedly compared with standard information. Hereupon, a marine observation instrument remote control system using the combination of FSK and ASK that was improved its controllability and movability was presented in this paper. Likewise, the logicality of control algorithm and remote control system were ascertained by experiments.

In this paper, we propose remote navigation control for intelligent robot using particle swarm optimization(PSO). The proposed system consists of interfaces for intelligent robot navigation and user interface in order to control the intelligent robot remotely. And communication interfaces using TCP/IP socket is used. To do this, we first design the fuzzy navigation controller based on expert's knowledge for intelligent robot navigation. At this time, we use the PSO algorithm in order to identify the membership functions of fuzzy control rules. And then, we propose the remote system in order to navigate the robot remotely. Finally, we show the effectiveness and feasibility of the developed controller and remote system through some experiments.

This study was performed to avoid the chemical spraying environment condition during spraying operation for operator's safety through the development of a remote controlled speed sprayer. The summerized results of this study are as followings. 1. The developed VHF electric wave remote controlling system which could operate sixteen type of operation conditions with the circuit channels of 234 was highly adaptable to speed sprayer for the remote control. 2. The commerical wireless telephones adapted the DTMF type electric wave remote control system need not the tranceiver. 3. The wireless electric wave remote control system combined with one-chip microcomputer, which are low cost with compact in size, could be adaptable to the remote control of the speed sprayer for the wheel steering and speed control system, and to the remote control chemical application system.

At present, some evolutional system has been used to promote the efficiency of the DNC(Direct Numerical Control) Controller. However, these are many inconvenience to this operator because it lacks harmony in interaction between the computer and the NC(Numerical Control). Also, there are some controversial poults when data error occurs at the Data Input/output. According1y, this thesis explores a new Data Remote Control System. In this study, the NC Controller of the DNC network has to Bet full data by removing data error in this system. In this system, the main merits are easy manufacturing and the convenience of Data Input/output. That is, remote control of the NC machine tool is possible without mutual interaction between the computer and itself.
